1) Load acc. To DIN 45921 on PCB. limited by temperature of solder area (competitor data often too high)
With suitable heat dissipation higher power rating is possible.
Diagrams for over temperatures available on request.
2) TC/50: Temperature range + 25°C...+ 125°C
Zero-Ohm-Jumper: :< 50 mOhm. TCR max. + 4000
